Starting today, I'm going back to @code + Copilot instead of Cursor. I've heard from many people who have been praising the latest few iterations of Copilot. The last time I tried it, I didn't like it, but it's been a few months since then. In general, using @code is better…

🆕 Releasing the entire MCP track! We curated the best talks and must-know topics in the MCP world from 1H 2025: - @chu_onthis, Anthropic: MCP's Origins + Startups - John Welsh, Anthropic: shipping Remote MCPs - @altryne (W&B) + @bhelx (Dylibso): Observable .tools for MCP -…

If you're building an MCP server, the latest version of VS Code is, in my opinion, the best IDE for debugging. It implements the full MCP spec but also has an "MCP Development Mode" that automatically restarts the MCP when changes are made and sets up debugging sessions for you.

Today we’re releasing GitHub Spark — a new tool in Copilot that turns your ideas into full-stack apps, entirely in natural language.

A week and half ago we asked you for feedback on Copilot and what we could improve in @code. Hundreds of you responded. Here is an update on what we've done since then regarding your feedback...

hot take: @code is the best AI tool for automating things that have nothing to do with code.

1/ Did @code just open-source-bombed us with @GitHubCopilot chat extension? Short answer - I think so!!!! Long answer - read the thread - link at the end here's my DeepWiki based analysis of: 1. System Architecture and Operation 2. Strengths vs Weaknesses 3. And more... 👇

🚀 We're hiring a Senior PM to bring AI superpowers to VS Code! Impact 50M+ developers. Ship daily. Build the future of coding with AI. Looking for a technical PM who can code & loves moving fast: jobs.careers.microsoft.com/global/en/job/… Questions or know someone perfect? DM me!

As promised, @GitHub Copilot went open source today. The coolest thing is you can now read and edit the system prompt for the coding agent. I can't wait to see the community go crazy with experiments, tests, and modifications.

Copilot in @Code is officially open source. Join @roblourens in 20 mins to see how you can get started with the repo TODAY. Link in comments 👇

Sometimes our incremental rollouts mean big features slip in quietly. But this one's worth the 🎊 fanfare: ✨ Agent mode powered by Claude Sonnet 4 is now the standard experience in VS @Code Chat. (Yes, Insiders, you've had this for a while!) Welcome to the agentic era.

We have a blog post out by @digitarald, @ConnorPeet & I talking about @code's complete adoption of MCP! It's a quick overview of the core components of this protocol. Lmk what you think! code.visualstudio.com/blogs/2025/06/…

If you upgrade VS Code and the GistPad extension, then Copilot chat can now automatically read/edit your gists, without any additional setup (via a built-in npmjs.com/gistpad-mcp). This is pretty fun because it makes your personal knowledge base even easier to use/manage
